Abstract

In late March of 2017, Quantum Spatial (QSI) was contracted by the Oregon LiDAR Consortium (OLC) to collect topobathymetric Light Detection and Ranging (LiDAR) data in the early spring of 2017 for the New River, OR site along the southwestern Oregon coast. The area of interest stretches along New River, which runs parallel with the Oregon coast. Data were collected to aid OLC in assessing the topographic and geophysical properties of the study area along the river’s course. The horizontal datum for this dataset is NAD83 (2011), the vertical datum is NAVD88, Geoid 12A, and the data is projected in UTM Zone 10 North. Units are in Meters. Quantum Spatial collected the New River, OR Topobathymetric LiDAR data for the Oregon LiDAR Consortium on 04/04/17.

NOAA's Office for Coastal Management received the associated LAZ files from OLC and processed them to the Digital Coast's Data Access Viewer, converting to geographic projection and ellipsoidal heights. A bare-earth digital elevation model was also received and is available, see the Related Items section, below.

Data Quality

Vertical Positional Accuracy:

The Non-vegetated Vertical Accuracy (NVA) of this dataset, tested at 95% confidence level is 0.034 m. Please see the LiDAR data report for a discussion of the statistics related to this dataset.Quantitative value: 0.034 m, Test that produced the value: Non-vegetated Vertical Accuracy was assessed using 19 ground check points. These check points were not used in the calibration or post processing of the LiDAR point cloud data.
Completeness Report:

LiDAR data has been collected and processed for all areas within the project study area.
Conceptual Consistency:

Shaded relief images have been visually inspected for data errors such as pits, border artifacts, and shifting. LiDAR flightlines have been examined to ensure consistent elevation values across overlapping flightlines. The Root Mean Square Error (RMSE) of line to line relative accuracy for this dataset is 0.025 m. Please see the LiDAR data report for a discussion of the statistics related to this dataset.

AGL: 372 m

Speed: 110 knots

FOV: 40 degrees

Scan frequency: 50 hz

Pulse rate: 245 kHz

Pulse duration: 1.2 ns

Pulse width: 0.26 cm

Wavelength: 532 nm

Pulses in air mode: Multiple Pulses in Air

Beam divergence: 1 mrads

Swath width: 290 m

Overlap: 60%
Process Date/Time: 2017-04-04 00:00:00

Process Step 2

CC ID: 1143261
Description:

Processing Steps (software used):

Resolve kinematic corrections for aircraft position data using kinematic aircraft GPS and static ground GPS data. Develop a smoothed best estimate of trajectory (SBET) file that blends post-processed aircraft position with sensor head position and attitude recorded throughout the survey. (Waypoint Inertial Explorer v.8.6 POSPac MMS v7.1 SP3)

Calculate laser point position by associating SBET position to each laser point return time, scan angle, intensity, etc. Create raw laser point cloud data for the entire survey in *.las (ASPRS v. 1.2) format. Convert data to orthometric elevations by applying a geoid correction. (RiProcess v1.7.2 Waypoint Inertial Explorer v.8.6 TerraMatch v.17 )

Import raw laser points into manageable blocks (less than 500 MB) to perform manual relative accuracy calibration and filter erroneous points. Classify ground points for individual flightlines. (TerraScan v.17)

Using ground classified points per each flightline, test the relative accuracy. Perform automated line-to-line calibrations for system attitude parameters (pitch, roll, heading), mirror flex (scale) and GPS/IMU drift. Calculate calibrations on ground classified points from paired flightlines and apply results to all points in a flightline. Use every flightline for relative accuracy calibration. (TerraMatch v.17 RiProcess v1.7.2 )

Apply refraction correction to all subsurface returns. (LAS Monkey 2.2.6 (QSI proprietary) )

Classify resulting data to ground and other client designated ASPRS classifications. Assess statistical absolute accuracy via direct comparisons of ground classified points to ground control survey data. (TerraScan v.17 TerraModeler v.17)

Generate bare earth models as triangulated surfaces. Generate highest hit models as a surface expression of all classified points. Export all surface models as ESRI GRIDs at a 1 meter pixel resolution. (TerraScan v.17 TerraModeler v.17 ArcMap v. 10.2.2 )

Correct intensity values for variability and export intensity images of all returns as GeoTIFFs at a 0.5 meter pixel resolution. (ArcMap v. 10.2.2 Las Product Creator 1.5 (QSI proprietary))

CC ID: 1143262
Description:

NOAA/OCM received the data from DOGAMI in LAZ format . Data were in NAD83(2011) UTM zone 10N and NAVD88 (Geoid12a) vertically. All units were meters. For ingest into the Digital Coast Data Access Viewer data were converted to geographic coordinates on the GRS80 ellipsoid in meters.
